European sea level monitoring: Implementation of ESEAS quality control

One of the objectives of the European Sea-Level Service (ESEAS) is to provide access to quality controlled European tide gauge data for research and other uses. The ESEAS quality control is based on a common set of procedures for the quality control of observed sea level data, which to a great extent can be referred to those specified by the Intergovernmental Oceanographic Commission for the Global Sea Level Observing System. Quality control also extends to other information such as documentation of datum information, metadata, exchange format, application classification, and levels of quality control. In relation to tsunami-enabled tide gauges, quality control is related to the availability of data in real-time and the use of automatic control and analysis procedures.
